NOTE TO CABLE/TV INSTALLER

This reminder is provided to call the CATV system
installer’s attention to Article 820-40 of the National
Electric Code (U.S.A.). The code provides guidelines for
proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system
of the building, as close to the point of the cable entry
as practical.

■

When a fixed image (e.g. logos, screen menus, video game, and computer display) is displayed on the TV

for an extended period, it can become permanently imprinted on the screen. This phenomenon is known
as “image burn” or “burn-in.” Image burn is not covered under the manufacturer’s warranty.

■

In order to prevent image burn, avoid displaying a fixed image on your TV screen for a prolonged period

(2 or more hours for LCD, 1 or more hours for Plasma).

■

Image burn can also occur on the letterboxed

areas of your TV if you use the 4:3 aspect
ratio setting for an extended period.

IMPORTANT INFORMATION TO PREVENT “IMAGE BURN
/ BURN-IN” ON YOUR TV SCREEN

WARNING / CAUTION

To prevent fire or shock hazards, do not expose
this product to rain or moisture.
